The Runway Ends Table dataset is updated every 28 days from the Federal Aviation Administration (FAA) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). The Runways database contains runways in the United States and US territories with information on the physical characteristics of the runways. Not all runways in this dataset have geospatial locations associated with them, as this is not a required data element from the airport source. As a result, this database contains a polyline layer, a points layer and a table. The polyline layer contains runways that had corresponding runways ends. The points layer contains mostly heliports, but also non-linear landing areas. The table contains runways where geospatial information was not reported. The runways in the database are associated with the airports dataset on NTAD, showing runways for all official and operational aerodromes. This geospatial data is derived from the FAA's National Airspace System Resource Aeronautical Data.
